What is the exact value of tan -13pi/6 and also the explanation

mihalych1998 [28]

$tan\left(-\frac{13\pi}{6}\right)=-tan\left(2\frac{1}{6}\pi\right)=-tan\left(2\pi+\frac{1}{6}\piright)=-tan\frac{1}{6}\pi=-\frac{\sqrt3}{3}$

Find the value of the angle θ rounded to 1 DP.

kogti [31]

Answer:

Step-by-step explanation:

Sin 21 = $\frac{opposite side}{hypotenuse}$

Sin 21 = $\frac{BC}{15}$

0.3583 = $\frac{BC}{15}$

0.3583*15 = BC

BC = 5.3745 = 5.37 m

Tan ∅ = $\frac{opposite side}{adjacent side}$

Tan ∅ = $\frac{4}{5.37}= 0.7448$

∅ = tan⁻¹ (0.7448) = 36.67 = 36.7

One of the acute angles in a right triangle has a measure of 36.6°. What is the measure of the other acute angle?

Solnce55 [7]

Triangles equal 180 degrees total
It’s a right triangle so one of the angles is 90 degrees and we know another angle is 36.6
So 90+36.6= 126.6
180-126.6= 53.4
So I’m assuming the correct answer is C since that’s the closet number to 53.4
